Sienna Miller made a rare red carpet appearance with partner Oli Green on Friday, May 15 2026 as the couple enjoyed a glamorous evening out in New York City following the arrival of their second child together.
The actress confirmed the news of her new addition in an interview published on 11 May, gushing that she is “madly in love” with the newest addition to her growing family.
“It’s happened. I have a tiny baby next door,” Sienna recently told E! News. “It feels like stringing sentences together is a bit challenging. I’m on very little sleep but I’m madly in love with my baby.”
The star, 44, attended the world premiere of Amazon MGM’s Tom Clancy’s Jack Ryan: Ghost War at Regal Times Square, where she posed alongside Oli and fellow stars including John Krasinski, Michael Kelly and producer Julie Rappaport.
For the occasion, Sienna embraced understated elegance in a flowing strapless grey gown featuring a softly structured silhouette and oversized draped design. The chic minimalist dress fell effortlessly to the floor and was paired with white pointed heels, statement silver earrings and sleek pulled-back hair that highlighted her glowing makeup.
Oli, 29, complemented Sienna’s sophisticated look in a tailored light grey suit teamed with a striped shirt and matching tie. The actor and model wore his signature tousled curls loose, with the couple appearing relaxed and affectionate as they posed together on the carpet.
The outing marks one of the pair’s most high-profile appearances since welcoming their daughter in 2024. Sienna is also mother to daughter Marlowe, whom she shares with ex-partner Tom Sturridge.
Sienna and Oli have been together since 2021 and have gradually become one of the fashion world’s most quietly admired couples thanks to their coordinated style and low-key approach to fame.
Professionally, Sienna has continued balancing motherhood with a successful acting career spanning more than two decades. After first rising to fame in the early 2000s through films including Layer Cake, Alfie and Factory Girl, she went on to earn acclaim for performances in projects such as American Sniper, The Loudest Voice and Anatomy of a Scandal.
Meanwhile, Oli has steadily built his own acting career while also working in the fashion industry, though he has largely stayed out of the spotlight compared to his famous partner.
The event celebrated the upcoming Jack Ryan project starring John Krasinski, with Sienna joining a stylish crowd of actors, producers and industry insiders for the premiere.
